Spindle apparatus; tension arrangements; bobbins.-Relates to yarn guiding and tensioning means for delivery apparatus wherein the yarn is locked and two twists are imparted thereto for each revolution of the apparatus, and comprises a tubular member 5 pierced at 7, 8, Fig. 2, through which the yarn passes as shown, or provided with pegs or with spring- controlled slats 19, 20, Fig. 3, and is arranged so as to extend in line or substantially in line with the axis of the bobbin. The device may be arranged in the bore of the bobbin, as shown, or may be integral with the bobbin, and then obviates the use of supports extraneous to the bobbin or spindle, but it may be arranged to be supported by the frame that weights the bobbin to prevent rotation, and may be utilised in the type of apparatus wherein the bobbin is mounted in a quadrilateral frame or closed flyer. The bobbin may be recessed and fitted on a sleeve 10 spanning the outer races of ball bearings carried by a comparatively short extension 12 of the rotary spindle, or the outer races may be fast with the spindle and the inner races carried by the bobbin support, or the bobbin may be provided with an extension adapted to fit the bore of the inner races, which may be joined by a sleeve. The means for mounting may be arranged in the manner described in Specification 287,338, the ball bearings therein described being dispensed with if desired. A weight 14 is provided to prevent rotation of the bobbin and to balance it. Two or more packages of yarn may be carried by the device so that the yarns therefrom are twisted and cabled. The device may be mounted substantially vertically, being inclined only so much as to allow the weighting- means to function.

Title: Improvements in or relating to apparatus for adding together two decimal numbers
IPC: G06F7/494
Filed: 1961-08-16
Abstract: 945,417. Coded decimal adders and subtracters. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Aug. 16, 1961 [Aug. 16, 1960], No. 29559/61. Heading G4A. In an arrangement for adding or subtracting binary coded decimal numbers in parallel, the decimal digit "6" is added or subtracted in each order to bring the result of the operation to the correct form. For adding two numbers, the respective digits, together with "6" are added and "6" is subtracted in those decimal orders which have not led to a carry. For adding a positive and a negative number, the negative number is presented in complement form, the corresponding digits are added, and when the result is positive, "6" is subtracted from those orders which have not led to a carry. The arrangement is applied to a parallel computer controlled by a microprogramme adapted to carry out the required programme steps. Fig. 1 shows a programme chart for adding numbers a,b. The signs of the numbers are compared at (a) and if equal and positive, a bi-stable flip-flop K is set to its "1" state. If both are negative K is set to "0" and a and b are complemented. (e) The digits are now added together with "6" in each order to form a sum #<SP>1</SP> which is inverted at (f) to form #<SP>11</SP>. (g) "6" is now added in all order which have produced no carry to form #<SP>111</SP>. If K is set at 0, this is the required answer but if K is "1", a further inversion at (i) is required. If a and b are of different sign, their algebraic sum #<SP>1</SP> is formed at (k) and if this is positive steps (f) &c. are carried out. If #<SP>1</SP> is negative, "6" is added in those orders which have led to a carry to give the answer at (m). The computing circuits described comprise an accumulator AC, an auxiliary register MD a carry register UB, the registers consisting of bistabel transistor stages (Fig. 5 not shown), and a programme control register SK comprising transistor amplifier circuit stages (Fig. 6, not shown). The register SK controls a microprogramme network (Fig. 7, not shown) adapted to control the required operation steps. The calculating circuit includes also a switching plate (Fig. 4 not shown), for each binary place, the plates being made of insulating material and having conducting horizontal and vertical lines on respective sides, the lines on one side of all the plates having plug connections to a socket plate (Fig. 3, not shown) which is also connected to the control register SK, Fig. 2, the outputs from which are thereby connected to each switching plate.

Abstract: 688,986. Weighing-apparatus. BLAW KNOX, Ltd. Dec. 5, 1951 [Dec. 5, 1951]. No. 29749/50. Class 143. Relates to transportable concrete &c. mixing machines in which a skip is supported on a weighing mechanism during loading, the loading section being so connected at one end to the mixing drumsupporting frame, that it can be folded upward when the machine is to be transported. In the embodiment described the loading section comprises frame members 5, 12, Fig. 1, on each side of the skip 34, supported by adjustable feet 13 and connected by cross members. A ball- and-socket joint 9, 11 connects the upper cross member to a cross bar 4 joining links 2 pivoted at 3 to the main framework of the machine 1. The skip, during loading, is supported on cross tubes 17, 18 joining side links 16, the ends of which are suspended from the lever system 19, 20, 23, 24, 29, which is attached to members 5 by straps 27, 28. The levers of the system on the side of the skip, not shown, are shorter, the two lever systems being connected by cross members 22, 26. Lever 20 operates the weight-indicating dial 32 through rope 31, the dial being supported on rubber pads 34 from the main framework. When the skip is raised by rope 38 for discharging, U-shaped brackets 40 attached thereto pivot about the cross members 18 until further brackets 37 engage the fixed shaft 36, whereupon the skip is raised from the weighing mechanism to the discharge position. For transport, a chain is attached between lugs 41 on members 5 so that raising the skip causes the whole loading section to fold about the axis 3 against the side of the machine. The pivotal connections between the links and levers of the weighing mechanism each employ ball or roller bearings. Thus the link 24, Fig. 4, is secured on a pin 43 the ends of which are carried in ball races 44 mounted respectively in the lever 23 and plate 45. The link 24 passes through an opening 49 in the bottom member 48, connecting the lever 23, and plate 45, and a rubber boot 50 seals the opening to prevent ingress of dirt.
